Need to check for a computer virus but don't have antivirus software installed? Try these excellent online virus-scanning tools. from Makeuseof.com .
You've likely had some experience with a computer virus or malware. If not, you're one of the lucky ones. But you can never rest—especially if you're running Windows.
Online free antivirus apps are no match for a standalone antivirus tool. Let's make that clear. However, an online antivirus scan is a handy tool in a pinch. Perhaps it is an unfamiliar PC acting strangely? Or the computer of a relative acting up? It's time for a virus scan.
The Best Online Antivirus Scanners
The best online antivirus scanners offer a full system scan, analysis, and file removal. However, it is important to note that an online virus scan cannot replace an offline antivirus suite. Online scanners do not offer real-time analysis and protection, so you cannot rely on them to keep your system secure. Instead, you should check out the best antivirus software for real-time protection.
It's also worth noting that online virus scanners still require a small download. Otherwise, the tool won't have access to your computer to scan for malware. Each of the following online virus tools have a portable download, which means you don't need to install any files; you just run the downloaded antivirus file, and the scan will begin.
1. ESET Online Scanner
This is handy if the online antivirus scanner throws up false positives.
2. F-Secure Online Scanner
Of the free online antivirus scanners, F-Secure Online Scanner is the most basic. You don't choose which files to scan; the Online Scanner covers your entire system. Given the speed of the scan, it isn't an issue. The lack of options has a plus side, too: F-Secure Online Scanner is incredibly easy to use.
3. Trend Micro HouseCall
Trend Micro HouseCall is a useful online virus scanner that provides a fairly comprehensive scan of your machine. Better still, you can use HouseCall on Windows and macOS, so you're not limited by operating system.
As with all online virus scanners, the Trend Micro HouseCall interface is simple to use; you download the launch file, run it, and start scanning. The Smart Scan function will rapidly analyze the places malware is most likely to lurk and, once done, provide a review and quarantine option to help you cleanse your system.
Individual Malicious File Scanners
Individual malicious file scanners differ from online antivirus scanners in that you provide a single file sample instead of scanning your entire system for malware or otherwise. The onus is on you to scan a file before executing it on your system, rather than quarantining after the infection takes place.
However, you can determine if a file is malicious and what is wrong with it while helping security researchers update their definitions.

What Is the Best Online Antivirus Tool?
If you want a rapid online scan with great results, try F-Secure Online Scan. It is easy to use, takes minutes, and hits the majority of malware.
